Yep, title,
I can play matches just fine, join em, join session, all of that.


But when my friends send me invites and I accept them, I always get "Unable to connect to host", likewise for them when I send them invites.

If you know what this is..
My NAT type is Type 2 and my UPnp is available/open.

Any help would be appreciated, also, my router is a Belkin F5D8233-4v3

And weirdly, it's JUST MW2 that does this..
In RE5 me and my friend connect just fine.
